ERBB2 and cancer: As a result, traditional cancer-associated pathways, such as cell cycle, Wnt signaling pathway, E2F transcription factor network, DNA damage, p53 pathway, EGFR signaling, FGFR signaling, ERBB2 signaling, PDGFR signaling, and PI3K-Akt signaling pathway were mostly associated with the 65 genes.
